Sandy Weill, the former CEO of Citigroup and father of the modern too-big-to-fail bank, last month shocked Wall Street when he said that he thought it might be a good idea to break up the megabanks like the one he used to run.

He's not alone in reversing his position. Former Merill Lynch CEO David Komansky, former CEO of CitiCorp John Reed, former CEO of Morgan Stanley Phil Purcell have also expressed doubts about the banking model that helped make them rich.

Their reasons for questioning too-big-to-fail vary. Purcell, for instance, merely opposes megabanks because he says shareholders would get more value if different banks were broken up. Others, like former Citigroup CFO Sallie Krawcheck, say it's the incentive structure of too-big-to-fail banks that is the problem, not their size.
